Amr bin Maymun al-Aw'di عمرو بن ميمون الأودي أبو عبد الله · The Book of Hajj

"I came to the Prohet in Jam (Al-Muzdalifah) and said: 'O Messenger of Allah, I have come from the two mountains of Tai and I did not leave any mountain but I stood on it; is there Hajj for me?' The Messenger of Allah said: 'Whoever offers this prayer with us, and stood before that in Arafatat by night or by day, his Hajj is complete, and he has completed the prescribed duties.'"
